    avutil/vulkan: avoid crash on null vkGetDeviceQueue2

    vkGetDeviceQueue2 is core since Vulkan 1.1 and is always loaded by
    ff_vk_load_functions() regardless of which extensions are enabled, but
    some drivers/loaders can still return a non-functional dispatch entry
    for it depending on how the instance/device were set up (e.g. an
    imported device from an app that declared an insufficient
    VkApplicationInfo::apiVersion). Calling it then crashes instead of
    failing cleanly. Guard the call and return AVERROR_EXTERNAL if the
    function pointer is unavailable.
